Hubert H. Humphrey Metrodome
The Hubert H. Humphrey Metrodome is now once again part of the Minneapolis skyline thanks to a new roof from Birdair.
Fabric Type: PTFE Fiberglass
Market Sector: Stadiums / Arenas
Project Size: 700,000 sq.ft.
General Contractor: Barton-Malow Construction Management
Completion Date: August 18, 2011
After a snow and ice storm caused the facility's previous roof to deflate and tear in December 2010, Birdair fabricated and installed a new roof on an aggressive five-month timeline. The company installed the Metrodome's original roof in 1982 and replaced the structure's 10-acre roof with more than 700,000 square feet of PTFE fiberglass outer and liner membrane material. The new roof looks similar to the old roof, but features a lower profile.
The roof's outer layer is PTFE SHEERFILL®, the first and only ENERGY STAR® qualified and Cool Roof Rating Council (CRRC) certified architectural fabric membrane that helps reduce surface roof temperatures and decrease heat absorption. As an ENERGY STAR product, SHEERFILL helps to lower air-conditioning requirements, reducing peak cooling demand by approximately 10-15 percent.
The installation crew consisted of Birdair supervisors, local ironworkers, laborers and equipment operators. The work began in March 2011 and was completed ahead of schedule in July 2011 in time for preseason football games.
